^^^^ I was wondering the same thing - what bolts were referred to?

Is there an easy way for someone who is looking at a used C7 to get a dealer to check to see if it's ever been tuned? I know it's most likely a small percentage of cars that are ever tuned, but if it's easy to check it would be a good idea.

OP, best of luck in getting some sort of relief. I'm with others that believe that the selling dealer most likely didn't know the car had been modified, but if they sold it to you representing that it had the remainder of the factory warranty they should accept some responsibility.

I'd ask the dealer you bought it from to do the repair and share the cost. I think you pay for the parts and they eat the labor. I'd also ask if you can then have a warrantee put back on the car......

The dealer should step up and help you. If the dealer bought this car at a Manheim owned auction and the car was sold with no announcement about tune or performance upgrades the dealer may be able to take the car back to the auction for refund.

I don't know, usually it is Buyer Beware. If I'm going to spend 5 digit figure on a car I will definitely make sure it is cleared by a GM dealer.

Engine was probably failing when the original owner traded it in. Last dealer thought he had a deal so bought it.

If the dealer you purchased it from certified the car, then it's on them for not catching this. I would put this back on them to handle. Good luck, let us know what happens.

I'm guessing lowering bolts.

Best of luck with this, but I've seen similar situations that didn't end well. If you bought from a GM dealer, you'd have a better case with GM corporate. I had an issue with an almost-new CPO Audi A7 and Audi corporate stepped up only because it was purchased from an Audi dealer and was CPO.

Here is the key words "from a non GM dealer, out of town" was it a major brand dealer or a Used car lot? How far out of town are you talking. If you could prove the tune was done prior to your purchase I would think it's on the selling dealer, but you need some way to prove that point.

Depending upon your state the AG's office may help you through a consumer fraud complaint. Sometimes getting the state office involved is enough that a dealer will unroll the deal rather than fight.

GM has rolled out what may well be an uncrackable ECM on the newest line of Duramax diesel pickups and they will soon roll it out across the other lines. This will be a double edged sword because although it will offer more protection to used car buyers from getting a nasty surprise it will also make it very difficult for owners to modify.

Although getting a dealer to inspect the car prior to purchase should uncover modifications you need to make sure that the inspecting GM dealer (and not some other shop) actually goes through the same process that they would when getting authorization for a major powertrain warranty repair. Otherwise you may get a quick look that says "all OK" when in fact it has been tuned and if they miss it you are still screwed because 3 months later when it fails the shop will claim it was tuned in the interim. Get a record of the same snapshot data sent to GM for warranty authorization. Of course any signs of engine work without corresponding warranty records, headers, missing cats, etc. are a huge red flag. Note that aftermarket warranties ride on top of the existing factory warranty and if the underlying warranty is blocked by GM then anything riding on top of it is also void so a third party warranty is also worthless on a modified vehicle.

Yup.


I heard about this being in the works.

FWIIW, I purchased my used '13 C6 from a non-GM dealership and the pre-purchase inspection was done by a Chevy dealership. Part of PPI included a diagnostic check to confirm that the car was set to factory specs and had never been tuned as of the date of the inspection. Also requested printed documentation to substantiate findings. Car was set to factory specs and no history of previous tune. $200 well spent since the car had about 8 months of factory warranty remaining. Hope this helps.

OP, terribly sorry to hear about your situation and hopefully you will be able to achieve a satisfactory resolution...

Very true and I think you are screwed on this. Go back to the selling dealer and see if they will stand behind the car since they sold you it with the understanding it had a warranty.

No I don't think it is that easy!

It doesn't work this way. In order for a new ECM to function in a C7, it must be programmed by GM's network computer using the vehicles vin. This can no longer be done with a Tech 2. Since this can only be done at a dealership, there will a record of an ECM replacement in GM's computer network. No dealer will replace your ECM just because you ask him to. Also, the ECM must be married to the BCM which is another issue altogether.

Buying used sports or perfomance cars is risky, as I've said here before. You pay your money and take your chances. Genuinely sorry to hear your plight, but...

That dollar figure for having a GM dealer tech check the car's computer for tune is close to what I had in mind as to cost and answer to Hopper's question. As said above by Yaupon, it's probably small number of cars that have a tune, but if it's the one you buy it can turn out badly.

You can see I’ve been on this forum for a long time. Haven’t posted too much overall, but I’ve done an extensive amount of reading and have learned an awful lot. I’ve seen many cases similar to mine and the OP here. I’m not a complainer, so I simply am doing what needs to be done to get my car back. I just think it’s comical that I’m getting the setup I am for similar or less money than a gm crate motor. Maybe the OP will look into tsp also..

Happened to me before. It stings a bit, when you get the bill and no warranty there to kick in.
